WIRE-TWISTING DEVICE.

Application filed March 10, 1910.

To all whom it may concern:

Be it known that I, DAVID IV. MARSHALL, a subject of the King of GreatBritain, residing at Sarnia, county of Lambton, Province of Ontario,Dominion of Canada, have invented a certain new and useful Improvementin ire-Twisting Devices, and declare the following to be a full, clear,and eXact description of the same, such as will enable others skilled inthe art to which it pertains to make' and use the same, reference beinghad to the accompanying drawings, which form a part of thisspecification.

This invention relates to tools for twisting wire.

It has for its object an improved tool adapted to be used for producingthe twisted wire that is used in pole line construction, the twistedwire being used mainly as a guy wire to brace or tie the poles of a lineof pol-es in their proper upright position.

In the drawings :-Figure 1 is a plan View of the tool showing the wirein the process of twisting. Fig. 2 is a side elevation of the twistingpart of the device. Fig. 3 is a sectional view of the twisting part ofthe device on the line aa of Fig. 2.

The device consists of a twisting head or frame adapted to be securedto'any suitable object, as for example, one of the posts that has beenalready erected in the construction of a pole line. In connection withthis is used a hook adapted to be secured temporarily to a distant post;the wire to be twisted is strung between the hook and the twisting head,and the desired amount of twist is given to it, after which it isremoved from the tool and applied to its place of ultimate use. Theremoval is effected generally by cutting the wire from the hook andeither disengaging it from the twisting head or cutting it, as may bemost convenient.

K indicates the hook, which may be of any size and shape suitable to beattached quickly to any object. It is provided with an eye M throughwhich the wire J to be twisted is run and doubled on itself to make adouble strand of a length suflicient to produce the finished twistedwire.

The twisting head consists of a body member B provided with a hook Dpivoted to one end thereof, and with prongs, spurs or points a which areof any number suitable for the desired security, and which project fromthat side of the body on which the body of the hook D lies. Upon thebody 13 Specification of Letters Patent.

is secured a stud bearing for a gear wheel E, and through the body ofthe twisting head nearer its end than the stud c is a rotatable shaft H,provided with a pinion F that meshes with the gear E, which terminateswith an eye it at its free end. A crank and handle G are secured to thehub of the gear E, and by means of this the gear and pinion may beturned for the purpose of twisting the wire G.

In use, the wire to be twisted is run through the eye M of the hook K,the hook K is made secure to any suitable object, as pole L. Asuflicient quantity of wire for the desired purpose is drawn through theeye M, the ends brought together and pass from opposite directionsthrough the eye it of the shaft or spindle H. The free ends of the wireare brought back and secured against escape from the eye h. The body ofthe twisting head is placed against any suitable holding device, as apole A, and the spurs c, or some of them, driven in until the body isheld against slipping or twisting around the sustaining post. The hook Dis then brought against the post and forced into it sufficiently to holdthe head with the requisite amount of security, after which the twistingprogresses by turning the handle G. It is, of course, necessary for theoperator to provide for the shortening of the wire by giving to theuntwisted wire suitable slack, so that the finally twisted wire is ofthe desired length.

What I claim is 1. In a wire twisting device, in combination with a basemember, an anchorage hook pivoted at one end thereof, whereby the samemay be removably attached to a post, a pair of shafts rotatablyjournaled in said base member adjacent the opposite end thereof from thepoint of pivoting of the anchorage.

hook, one of said shafts being pierced at one end for the engagement ofa wire therethrough, intermeshing gear wheels mounted 011 said shafts,and a crank for actuating the same, whereby rotative movement may becommunicated to a loop of wire passed through the pierced end of one ofthe shafts, substantially as described.

2. A wire twisting device, having in com bination with a base member, ashaft having a pierced end journaled therein, a second shaft providedwith an actuating crank journaled in said base member, a pair of gearwheels carried by said shafts in intermeshing position with respect toone another, In testimony whereof, I sign this speciwhereby said piercedshaft and a loop of fication in the presence of two Witnesses. wire en ain therethrou 'h may be posi- 7 y tively r ta tedf and an anchorage hookpiv- DAVID MARSHALL 5 oted t0 the opposite end of said base Inem-Vitnesses:
